Arsene Wenger has declared every time Arsenal fail to win is a "disaster" - and has no intention of feeling any emotion other than triumph against Hamburg in their Champions League clash on Tuesday night.

Last season's European Cup finalists are in real danger of failing to make it to the knockout stages, currently level on points with Porto and one behind leaders CSKA Moscow. Hamburg, meanwhile, are bottom of Group G, their fate already sealed following four straight defeats.

The Arsenal boss declared: "Every time Arsenal do not win, for me it is a disaster. Every game we do not win is a real disaster because we want to win every game."
